Came in 2 days as promised with the excellent Amazon Prime to my front door under the eaves so that it wouldn't get soaked in the sudden winter storm - so extra props to the delivery service too - I was worried I would come home to a melted box.The pieces were nice heavy wood. Instructions were not very clear but the pieces were easy to assemble nonetheless. As others have pointed out, the instructions call for two people to put this together. I am not very handy and was able to do it by myself very slowly in under 2 hours in a very small work-space.The included tools - the set has all the required screws, little wood pegs, and some glue. The glue was pretty low/standard quality, if I had to do this again I would definitely purchase some carpenter's glue before tackling the setup. The wood pegs are not very strong and several broke mid construction when I tipped to an angle to lock in the other side. Every shelf is attached to a "leg" by three holes (2 for wood pegs and middle hole for metal screw) on each side so the breaking pegs did not alarm me that much. Make sure you have a mallet/hammer, screwdriver, philips head screwdriver, and wet cloth to wipe everything down.The two "parts" of the bookshelf consist of the top with 2 shelves and the bottom with three shelves - assembled in pretty much the same way. There is small "foot" piece that attaches to largest bottom shelf.My star deduction and biggest concern about the unit is that one of pre-installed pegs on the the leg (there is two on each side) do not fit into the the top portion of the shelf. So here I have one side (left) fitting perfectly and the other side where one peg fits correctly and the other one about 10-15 degrees off to the wrong angle. By then I had reached close to the 2 hour mark and had nearly the whole thing assembled so I decided to saw off the rogue peg. Now my top and bottom pieces are secured with three wood pegs and two horizontal long screws.The shelf is holding so far - I'm using it as a liquor shelf with the upper ones for wine glasses. Weight testing to see if it will hold its shape in 2 weeks before I load it with the glasses. Also note, I don't know if this has to do with my poor skills, the two legs of the shelf were not parallel to the wall until I loaded items onto it.*Did not use the wall brace/brackets since it required both putting holes in my wall and possible drilling holes into the "legs" because otherwise I did not see any pre-drilled holes.Appreciate if anyone has tips for further securing the unit. This is really great looking shelf for the price!
